Animals are put to many uses in war. Sometimes they have jobs to do: the horses and donkeys used to transport soldiers and equipment, as well as tracker dog with their special talents. Often animals are used as mascots and pets. This set of images shows some of the animals that have served with Australians in wartime.

There are some mysteries is this set: how did a koala travel to Eygpt in 1915? Who is the man holding him? How did a kangaroo make it to Harefield in the UK in the First World War? How did that young man come to have a dog with him when he was evacuated from Tobruk in 1941?
